Residential Systems
and can be divided into off – grid and on grid systems .
Fred STED On – grid : Households could opt for an on – grid system where the power is generated during the daytime and fed directly into the household’s use to offset energy drawn from the grid . Should the household be unable to use all the power generated at a given time , called ” over – generation ” , the power would need to be fed into the grid , an aspect that is not yet fully operational on the South African grid .
Off – grid : Households generally consumes the most energy during the early evenings and mornings – the time of day when the sun does not produce optimal energy . Storage of energy through the use of batteries then becomes necessary . These systems provide the consumer the customer with the security of supply but do not necessarily result in a very cost – effective solution .
Agriculture Solar Energy
Agriculture Solar Energy ( Photovoltaics ) can be applied to a wide range of applications ; most important ones include irrigation , refrigeration of agricultural products , milling of grains , electric fencing , poultry lightning even pivot system irrigation . Although the application of solar PV ( photovoltaics ) system is limited to apparatus with smaller energy inputs , it will help you cut your dependency on electricity . Additionally , the cost of the PV systems is projected to decline over time .
PUMPS
Solar water pumping can provide significant environmental social and Economic benefits at farm and national levels . At the farm level , the technology can provide a reliable source of energy in remote areas . particularly areas that are not connected to the power grid or lack a regular supply of liquid fuels . At the national level , solar water pumping can help stabilize increase and diversify agricultural production which is the basis .of most African countries economies
Solar Pivot Irrigation System
Center pivot irrigation also called water wheel and circle irrigation is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers , a circular area centered on the pivot is irrigated . Center pivot irrigation systems are beneficial due to their ability to efficiently use water and optimize a farm’s yield . The Systems are highly effective on large land fields . In SDC we design solar system for pumps use in center pivot irrigation , as well as do accurate and optimal calculations of the pumps that you need to operate your pivot irrigation in your farm so we give you the best solution for solar system .
Telecommunication
In telecommunication we used PV system ( photovoltaics ) for powering signal booster towers .
